  封装的基于氨基酸的离子液体，用于二氧化碳捕集

  摘要：

  离子液体由于具有捕获二氧化碳的潜力以及作为缓解气候变化的溶剂的潜力而备受关注。遵循先前的工作范围，这里提出了将氨基酸基离子液体（ENIL）封装到碳质亚微囊中的建议，作为捕获CO 2的新型材料。使用乙酸四丁基phosph（[P 4,4,4,4 ] [Ac]）制备的ENILs作为参考，（2-羟乙基）三甲基铵-1-苯丙氨酸盐（[N 1,1,1,2（OH） ] [ -L-Phe的]），（2-羟基乙基）三甲基铵升-prolinate（[N 1,1,1,2（OH） ] [L-Pro的]），和四丁基升-prolinate（[N 4,4,4， 4] [L-Pro]）通过SEM，TEM，元素分析，TGA和BET进行表征，以评估其形态，化学组成，多孔结构和热稳定性。CO的吸收2在这些材料进行了研究最多至0.5MPa和343 CO的K.解吸2从饱和ENILs进行评价，在温和条件下，证明这些材料作为有前途剂CO

  A series of room temperature ionic liquids (ILs), in which cholinium acts as the cation and amino acids as the anions, were prepared via a simple and green chemical route, and characterized. Most of the ILs dissolved lignin efficiently and selectively (with solubilities of 140–220 mg of lignin per g of IL). The solubility of xylan in these ILs (which ranged from <1 to 85 mg g−1) depended on the nature of the anion, while cellulose was scarcely soluble (<5 mg g−1). In addition, enzymatic hydrolysis of microcrystalline cellulose and rice straw was enhanced significantly after pretreatment using the IL [Ch][Gly].

  一系列室温离子液体（ILs）被制备，其中胆碱作为阳离子，氨基酸作为阴离子，通过一种简单且环保的化学路线进行制备和表征。大多数ILs能够高效且选择性地溶解木质素（溶解度为每克IL 140–220毫克木质素）。这些ILs中木聚糖的溶解度（范围为<1到85毫克每克）依赖于阴离子的性质，而纤维素几乎不溶解（<5毫克每克）。此外，经过IL [Ch][Gly] 预处理后，微晶纤维素和稻草的酶解水解显著增强。

  Biobased ionic liquids with cholinium as the cation and amino acids as the anions, which could be prepared from renewable biomaterials by simple neutralization reactions, have recently been described as promising and green solvents. Herein, they were successfully used as the reaction media for enzyme-mediated transphosphatidylation of phosphatidylcholine with l-serine for phosphatidylserine synthesis for the first time. Our results indicated that the highest phosphatidylserine yield of 86.5% was achieved. Moreover, 75% original activity of the enzyme was maintained after being used for 10 batches. The present work could be considered an alternative enzymatic strategy for preparing phosphatidylserine. Additionally, the excellent results make the biobased ionic liquids more promising candidates for use as environmentally friendly solvents in biocatalysis fields.
